The aim of this study is to evaluate attitudes of family physicians antimicrobial prescribing. Materials and methods: This study was conducted in November 2006 in Bolu and Duzce provinces where the first family physician practices were initiated in Turkey. The records of family physicians were reviewed retrospectively. Patients’ data, social security institution of the patients, the diagnosis and prescribed antibiotics, duration, dosage and routes of antibiotic administration were recorded. Results: A total of 4,497 patients were included in the study consisting of 1,752 (39%) men, and 2,745 (61%) women. The mean age of the patients was 36.6 ± 22.7 years. Antimicrobials were prescribed to 1,167 patients (25.9%). Among 1,167 antibiotics, 1,064 (91.2%) were administered orally, 77 (6.6%) were paranteral and 26 (2.2%) were taken through other routes. In 39 (3.3%) patients, there was no indication for antimicrobial use. In 103 patients (9.1%) from the accurate antibiotic indication group, the choice of the agent was not consistent with the guidelines. In 273 patients (23.4%) on antimicrobial therapy, duration of the antibiotic was inappropriate. The most common indication of the antibiotic prescription was tonsillopharyngitis and the most prescribed antibiotics for this diagnosis were beta lactam/beta lactamase inhibitors. Conclusions: In conclusion, there is still considerable overuse of antibiotics by primary care patients, especially the ones suffering respiratory tract infections. Educational interventions on antimicrobial use could be useful.

Ancak bu ilaçların uygunsuz kullanımları sonucu ge-lişen antibiyotik direnci tüm dünyada giderek artan problemlerden biri olmaya devam etmektedir. Bu çalışmanın amacı, birinci basamak sağlık hizmetlerinde görev yapan aile hekimlerinin antimikrobiyal tedavi hakkındaki tutum ve davranışlarının araştırılmasıdır. Gereç ve yöntem: Çalışma, aile hekimliğinin ilk uygulanmaya başladığı yerler olan Bolu ve Düzce illerinde yapılmıştır. Aile hekimlerinin tanı ve tedavi kayıtları retrospektif olarak incelenmiştir. Hastaların demografik özellikleri, sosyal güvenceleri, konulan tanı ve reçete edilen antibiyotikler, antibiyotiğin veriliş yolu, süresi ve dozu incelenerek standart bir forma kaydedilmiştir. Bulgular: Çalışmaya 1752’si erkek (% 39), 2745’i kadın (% 61) olmak üzere toplam 4497 hastanın verisi alınmıştır. Hastaların yaş ortalamaları 36,6±22,7 idi. Toplam 1167 (%25,9) hastaya antibiyotik tedavisi verilmişti.

The term “rational drug use” was described at the World Health Organization conference in 1985 in Nairobi as “Giving medications appropriate to patient’s clinical needs, in doses that meet their own individual requirements for an adequate period of time, and at the lowest cost to them and their community”.1-2 While, cardiovascular drugs are the most consumed drugs worldwide, antibiotics are the most consumed drug groups in our country like the other developing countries.3 In infectious diseases, generally medical achievement is obtained with early diagnosis and rational antimicrobial therapy. Rational drug use is important in that it prevents complications, shortens the duration and severity of illness and survival. If community and hospital acquired infections are not treated effectively because of irrational antimicrobial use (unnecessary use, the wrong choice of antibiotic, wrong dosage and/or route), duration of the disease may extend.4 In addition, antibiotic usage in viral infections causes antibiotic resistance to increase and unnecessary expenditures.5 Different payment institutions such as Social Insurance Institution, Pension Fund, BAGKUR, and Green Card had operated in Turkey until 2005. However, after 2005, these agencies were put under one roof, and facilitated access to health services and drugs.6 This situation has led to increased consumption of all drugs, including antibiotics. Many studies have been conducted on the use of antibiotics in primary health care in our J Microbiol Infect Dis country. It was shown that the most common antibiotic consumption in primary health care was due to respiratory tract infections. Another common finding of these studies is the frequent and often inappropriate usage of antibiotics.7,8 Şaşmaz et al.9 detected that in a study examining records of the patients admitted to primary health care; patients were most often diagnosed with acute respiratory tract infection (32.4%) and mainly penicillins (56.1%), macrolides (21.9%), and cephalosporins (11.5%) were prescribed to them. The aim of this study was to investigate the attitude and behaviors of family physicians regarding antimicrobial therapy in Bolu and Düzce provinces where the family physician was practiced. MATERIALS AND METHODS This study was designed retrospectively and conducted in Bolu and Duzce provinces in Turkey, between November 2006 and January 2007 by collecting data from family physicians’ records. Düzce and Bolu provinces, which have a population of 323,328 and 271,545, respectively, are the cities located in the Western Black Sea region of Turkey.10,11 Both rural and urban area patients’ records of family physicians who accepted to participate in this study were investigated, after obligatory permissions were obtained from Bolu and Düzce Provincial Directors of Health. Patients’ demographic, social security information, diagnoses and used antibiotics, treatment duration, dose and routes of antibiotic administration were recorded on a standard form. By reviewing the records, diagnosis, treatments given to patients, administration routes and doses were compared with guidelines. Indication for antibiotics, appropriateness of antibiotic indication, compliance with treatment duration, and route of administration of the dose was assessed. www.jcmid.org Vol 1, No 2, September 2011 Karabay O, et al. Phamily physicians and antibiotic use RESULTS A total of 4,497 patients’ data were obtained during the study period. Of these patients, 1,752 (39%) were men and 2,745 (61%) were women. Their mean age was 36.6 ± 22.7 years. A total of 1,167 patients (25.9%) were on antimicrobial therapy. Only one antibiotic was written in each recipe in all patients. 2,911 (64.7%) patients’ social security institution status was achieved. While antibiotics had been prescribed to 708 of 2,596 patients who have social security, they were prescribed to 67/315 patients who are not covered by any social security institution (p<0.05). Out of the 1,167 antibiotics, 1,064 (91.2%) were administered orally, 77 (6.6%) were administered parenterally and 26 (2.2%) were administered through the other routes. Prescribed antibiotics and the rates of them are presented in Figure 1. According to our study results, tonsillopharyngitis was the most common indication for antibiotic prescribing (n=468, 40.1%). Beta lactam/beta lactamase inhibitors were prescribed to 52.1% (n=244) patients with this diagnose. Out of 55 1167 patients, 39 (3.3%) patients did not have any antibiotic indication. Also, in 103 patients (9.1%) among the true antibiotic indication, the choice of the agent was not in line with the guidelines; and in 273 patients (23.4%) on antimicrobial therapy, duration of the antibiotic was inappropriate (Table 1).

Parameter n (%) Antibiotics without indication 39 (3,3) Incompliance of antibiotic indication 103 (9,1) Incompliance of the treatment period 273 (23,4) The number of patients in the study 4497 The number of patients who received antibiotics 1167 (25,9) The most common indication for antibiotic use Tonsillopharyngitis n= 468 (40,1) The most commonly used antibiotics in tonsillopharyngitis DISCUSSION As in all over the world, antibiotics are prescribed in a high proportion in our country. For many years in Turkey, the most consumed drug group was antibiotics. When the drug consumption rates were evaluated according to therapy groups, it was seen that 20.4% in 1999, and 18.1% in 2002 were antibiotics.3 In 2010, out of the 1,570 million box used drugs, 223.8 million boxes were systemic anti-infectives.12 Unfortunately, irrational use of antimicrobials is a very common occasion. In other words, antiJ Microbiol Infect Dis Beta-lactam/beta-lactamase inhibitors (52,1) biotics are one of the most abused drug groups.5 In a study undertaken in Vietnam in 1997, researchers discovered that more than 70% of patients were prescribed with inadequate amounts of antimicrobials for serious infections. In China, researchers found that 63% of antimicrobials selected to treat proven bacterial infections were simply the wrong choice, while 50% of drugs dispensed in one hospital unit in Bangladesh were inappropriate. The same is true even for the countries like Canada and the United States which developed their antibiotic usage control mecha- www.jcmid.org Vol 1, No 2, September 2011 56 Karabay O, et al. Phamily physicians and antibiotic use nisms. In these countries, it is estimated that physicians over-prescribe antibiotics by 50%.13 be due to simple use from oral route and marketing techniques of drug industry. In our study, we determined that there was no antibiotic indication in 3.3% patient, and the choice of the agent was inappropriate to the indication in 9.1% patient among the true antibiotic indication. Furthermore, our findings revealed that the duration of the antibiotic was found inadequate in 23.4% patients. Drug expenditures play a major role in total health care spending of our social security institution. In our study, the amount of antibiotic prescription to patients who are covered by any social security scheme was found to be significantly higher than that of the patients who are not covered under any social security scheme Antibiotics were prescribed to 27% of patients who are covered under any social security scheme, while they were written to 21% of patients who are not. This data suggest that, economic status of the patients was considered when prescribing antibiotics and they were written more easily for patients who are covered under any social security scheme than those who are not. In our opinion, application of electronic tracking systems to patients covered under any social security scheme can help to rational antibiotic use. Antibiotics were used unnecessarily in many developing countries. This situation was shown in both primary health care facilities, and hospitals.14,15 In our country, 15-20% of all prescribed drugs are antibiotics. Antibiotics have been the most used drugs for many years. The main reasons of unnecessary usage may be related with insufficient medical education about antibiotics, pharmaceutical industrial pressure and promotions, absence of antibiotic policy, and absence of antibiotic guide for primary health care. Antibiotic overuse is an important problem for many countries. For example, in our study the most common antibiotic prescription indication was upper respiratory tract infections. However, we clearly know that only 20% of upper respiratory tract infections are bacterial. Many studies from our country showed that upper respiratory tract infections are the most common indication for unnecessary antibiotic prescription in primary health care facilities.16 It was reported that the most prescribed antibiotic groups in our country were; penicillins (67.8%), cephalosporins (36.6%), and macrolides (13.8%).17 The most prescribed antibiotic detected in our study was beta lactamase resistant penicillins with a rate of 33%. Cephalosporins (21%), quinolones (12%), and macrolides (12%) were the other most prescribed antibiotics in order. Panasiuk et al.18 indicated that, antibiotics are prescribed in approximately 87.5% of cases of pharyngitis and tonsillitis and the most preferred three antibiotics are amoxicillin (35.6%), amoxicillin-clavulanate (13.2%), and macrolides (10.4%). In our study, a total of 52.1% patient diagnosed as tonsillopharyngitis were treated with beta lactam/beta lactamase inhibitors. Similarly, this study showed that, beta lactam/beta lactamase inhibitors were the most preferred antibiotics in patients diagnosed as tonsillopharyngitis in primary care services. Preference of these drugs rather than penicillins in tonsillopharyngitis may J Microbiol Infect Dis Before any conclusion, we should declare that our study had several limitations. We used only retrospective patient cards. We did not make face to face meeting or a questionnaire survey with doctors. If we could interview with doctors to this study, our data would be more powerful. Conclusion Rational antibiotic use will continue to be explored and discussed in terms of their use for true indication, in sufficient period, and in a cost effective manner. It was seen that; significant part of prescribed antibiotics were not prescribed for correct indication, and among the antibiotics prescribed for proper indication, some of them were unnecessarily in broad spectrum and their duration was inappropriate. In order to ensure rational antibiotic use in primary health care, importance given placed on the use of antibiotics should be increased, and the focus on practical training, as well as theoretical knowledge in the course of medical education needs to be strengthened. Post-graduate training courses should be organized on common infections like the upper respiratory tract infections. In addition, laboratory facilities that contribute to the diagnosis in primary care should be increased. Consumption of antibiotics from pharmacies should be followed by an information system. www.jcmid.org Vol 1, No 2, September 2011 Karabay O, et al. Phamily physicians and antibiotic use REFERENCES 1.
